Sky News have said that the teams have agreed to cancel the planned pre-season test in Bahrain scheduled for March 3rd. No source was given so the accuracy of this statement cannot be guaranteed.
Adam Cooper's F1 blog has stated that the Crown Prince has called the season opener off and includes an alleged statement in relation to that decision. Given his history in the sport we'll take it that this is the case. This news is supported by Reuter's but has not yet appeared on the FOM website.
